I think you should learn to fill out the rest of the question.
And do your own homework.

in orbit, centripetal force=weight
mv²/r=GMm/r²
so
v²=GM/r
v=sqrt(GM/r)
where r is the orbital radius (earth radius+334), G is the gravitational constant (6.67E-27), M is the mass of the earth, and v is your orbital velocity.
